Gallons to Cups Converter

Convert US gallons to cups instantly using the exact ratio where one US gallon holds 16 cups. This is a practical kitchen and catering conversion, handy for scaling drink batches, punch, brine, or cooking liquids when a recipe gives a gallon total but you measure with a cup. Type any number of gallons, including fractions like 0.5, and the cup value appears live as you type. Note that this tool uses the US customary gallon and US customary cup, which are the most common online, and both differ from imperial (UK) units, so a UK gallon does not equal 16 UK cups in the same way. Because multiplying by 16 across fractional gallons is easy to slip on, the tool keeps you accurate. It runs free and instant in your browser, so it is private and works offline once loaded.
